Raw Data for the article: Transjugular Intrahepatic Portosystemic Shunt: A Single-Centre Mid-term Experience Using the Viatorr Controlled-Expansion Stent
<p>Authors reported a high incidence of hepatic encephalopathy (HE) using the Viatorr Controlled Expansion stent (VCX) (Gore, Flagstaff AZ) in a cohort of 33 patients underwent transjugular intrahepatic portosystemic shunt (TIPS) creation. In detail 6 and 12 month overall HE rate was 53% and 61%. Those results are different as compared to our preliminary experience, with the same stent, in which the overall HE rate was 22% in a cohort of 75 patients and with a mean follow up of 5.8 months.</p>
Gender-associated outcomes following percutaneous coronary intervention with a third-generation, ultrathin-strut drug-eluting stent: a real world, single-center experience.
<p>This record contains raw data related to the article: Gender-associated outcomes following percutaneous coronary intervention with a third-generation, ultrathin-strut drug-eluting stent: a real-world, single-center experience.</p> <p>ABSTRACT </p> <p><strong>Introduction.</strong> In recent years the new third-generation, ultrathin bioresorbable-polymer sirolimus-eluting stent (BP-SES), characterized by some of the thinnest struts among commercially available devices (60-80 µm) and an amorphous silicon carbide coating, has been introduced for the treatment of coronary artery disease (CAD). Aim of the present study was to assess different clinical outcomes and safety of this drug-eluting stent in male and female patients in a real-world setting.</p> <p><strong>Methods. </strong>The present study is a retrospective analysis including all patients treated with BP-SES between January 2017 and December 2019 at a single, high-volume center. Follow-up was performed by outpatient visit or by telephone contact. The main study outcome was target lesion failure (TLF), defined as a composite of cardiovascular death, target vessel myocardial infarction or target lesion revascularization.</p> <p><strong>Results: </strong>Overall, 66 (15.9%) female and 349 (84.1%) male patients were included; women were older (median age 70 vs. 66, p=0.003) and with lower BMI (25.0 vs. 26.1, p=0.010) compared to men, with no other relevant differences in baseline characteristics. Indication for percutaneous coronary intervention (PCI) was acute coronary syndrome in 86 (20.7%) of the cases, with no significant differences between male and female patients. A total of 558 lesions were treated with BP-SES stents, 90 in women and 468 in men (1.36 vs. 1.34 lesions per patient, p=0.83); cumulative stent length (33.6 mm vs. 38.4 mm, p=0.078) and mean stent diameter (2.92 mm vs. 3.0 mm, p=0.39) did not differ in women compared to men. Technical and clinical success was achieved in all patients. Stent thrombosis (ST) occurred in 2 (0.5%) patients, both males. TLF occurred in 10 (2.9%) men and in 2 (3.0%) women after a median follow-up of 402 days, without significant differences at log-rank analysis (2.34 events per 100 patient-years in males, 2.53 in females; p=0.80).</p> <p><strong>Conclusions. </strong>Ultrathin struts BP-SES showed a safe and effective option for the treatment of CAD in both women and men, with very low ST rate and favorable long-term outcomes</p>
Raw Data for the article: Right vs left portal branch puncture in TIPS creation with controlled expansion covered stent: comparison of hemodynamic and clinical outcomes
<p><strong>Purpose: </strong>To retrospectively compare outcomes of TIPS performed by puncturing left portal vein (LPV) vs right portal vein (RPV) to access the portal system.</p> <p><strong>Materials and methods: </strong>One hundred ninety-three consecutive patients underwent TIPS with controlled expansion covered stent by using the LPV (37 patients) or the RPV (156 patients). Patients were followed until the last clinical evaluation, liver transplantation, or death.</p> <p><strong>Results: </strong>Demographics and clinical characteristics of the two groups were comparable. The median follow-up was 9.6 months (range 0.1-50.6). Portosystemic pressure gradient (PSG) before TIPS 15.7 mmHg ± 4.7 in RPV group (RPVG) vs 15.4 mmHg ± 4.5 in LPV group (LPVG) (p = 0.725). After TIPS, PSG 6.3 mmHg ± 2.8 in RPVG vs 6.2 mmHg ± 2.2 (p = 0.839). In LPVG, the stent was dilated to 8-mm in 95% of patients vs 77% of RPVG (p = 0.015). Two (5.4%) and 22 (14%) patients underwent TIPS revision in LPVG and RPVG (p = 0.15). The incidence of overt HE was 13% in LPVG and 24% in RPVG (p = 0.177). Rebleeding occurred in 3 of 49 patients (6%) with variceal bleeding as an indication: 2/41 patients (4.9%) in RPVG vs 1/8 patients (12.5%) in LPVG (p = 0.417). Among 126 patients with refractory ascites 20 patients (15.9%) needed paracentesis 3 months after the procedure: 18/101 patients (17.8%) in RPVG vs 2/25 patients (8%) in LPVG (p = 0.231). Thirty-seven patients (19%) died: 32 (21%) in RPVG and 5 (14%) in LPVG (p = 0.337).</p> <p><strong>Conclusion: </strong>Compared with RPV puncture, in TIPS created through the LPV, the targeted PSG was reached with a smaller stent diameter. However, no significant difference in clinical outcomes was observed.</p>
Raw Data for the article: Clinical outcomes of transjugular intrahepatic portosystemic shunt with PTFE-covered stents after liver transplantation and technical results in split and whole liver graft recipients
<p><strong>Objectives: </strong>To assess the outcomes of transjugular intrahepatic portosystemic shunt (TIPS) creation using PTFE-covered stents in liver transplant (LT) recipients and to analyze the technical result of TIPS creation in split grafts (SG) compared with whole liver grafts (WG).</p> <p><strong>Methods and materials: </strong>Single-center, retrospective study, analyzing LT patients who underwent TIPS using PTFE-covered stents. Clinical and technical variables were analyzed.</p> <p><strong>Results: </strong>Between 2005 and 2021, TIPS was created using PTFE-covered stents in 48 LT patients at a median of 43 months (range, 0.5-192) after LT. TIPS indications were refractory ascites (RA) in 33 patients (69%), variceal bleeding (VB) in 9 patients (19%), others in 6 (12%). Ten patients (21%) received a SG. Technical success rate was 100% in both groups: in two WG recipients, (5%) a second attempt was required. An unconventional approach (combined transhepatic or transplenic access) was needed in 2 WG (5%) and 2 SG recipients (20%). Two procedure-related death occurred in the WG group. After a median follow-up of 22 months (range, 0,1-144), 16 patients (48%) in the RA group did not require post-TIPS paracentesis, in the VB group rebleeding occurred in 3 patients (33%). Fifteen patients (31%) underwent TIPS revision. Overt hepatic encephalopathy occurred in 14 patients (29%). Patient survival at 6 months, 1 year, and 3 years was 77%, 66%, and 43%, respectively.</p> <p><strong>Conclusions: </strong>The feasibility and safety of TIPS creation in SG are comparable to that of WG. TIPS creation using PTFE-covered stents represents a viable option to treat portal hypertensive complications in LT recipients.</p>
